In Palladium (Atomic no.-46), number of electron having $(ℓ = 2)$ will be -

Answer:

Solution:

Palladium (Pd) has atomic number 46. Its electron configuration is $[Kr] 4 d^{10}$ .

The quantum number $l = 2$ corresponds to the d-subshell.

In the $4 d^{10}$ configuration, there are 10 electrons in the 4d subshell.

Also, the Krypton (Kr) core has $3 d^{10}$ electrons.

So, total electrons with $l = 2$ are $10 (f ro m 4 d) + 10 (f ro m 3 d) = 20$ .

The final answer is $20$ .
